Fortunately, Alan has identified just one flower that is “easy” to maintain and will deliver a “summer of colour”. He suggests picking Osteospermum, which are also known as African or Cape daisies. They provide long-lasting, vibrant blooms throughout summer, extending into autumn.
Alan said: “Osteospermum is a perennial but it is tender. In the mildest gardens, those by the sea in the south west of England, they can come through the winter.” Alan suggests planting them in mid to late May.
He said: “You’ll get a whole summer of colour from these bright daisies.” In his Gardening with Alan Titchmarsh video, the expert had a yellow osteospermum, though they are available in an array of colours.
“There are others that are dark reds, deep burgundy, ones called Tresco Purple that I absolutely love,” he said. Beyond adding colour to gardens, the flowers are also great for bees.
In his video caption, Alan said: “This is also a great plant for wildlife. Bees and other pollinating insects are drawn to osteospermum because the central part of the flower offers nectar and pollen.
“That means the plant does more than add colour; it helps bring life and movement into the garden.” Gardener’s World has additionally published guidance on planting and cultivating osteospermum.
It is recommended that they be planted out following the final frosts, which typically occur in late May and early June. After the frost has cleared, they can be put in containers and borders.
“Plant with the top of the root ball level with the soil or compost, firm in and water well after planting,” Gardener’s World advised. They require regular watering until fully established.
Osteospermums in borders will manage with less frequent watering, while those in containers require consistent watering during warm spells. They should receive weekly feeding throughout the growing season with general plant food.
The plants are available as seeds, plug plants or garden-ready plants. Osteospermums can be brought indoors during autumn and winter if kept in pots.
